 Issue with the dashboard and the new database
I created a dashboard in JMP, and now I want to use it with a different database.
 I tried copying and pasting the dashboard, but it still opens the one from the other database.
 I also modified the data sources and renamed the file, but I'm getting an error.
 How can I solve this problem and use the same dashboard with a new database?

I would say this depends how you have built your script. Somewhere it is still referencing to the earlier database (or do you maybe mean data table?).

Use Show Properties:

and then change the setting for DataTable1 to Current Data Table:
